Genetic results from the Cholesky decomposition of the five aspects of mathematics. The five measured variables (rectangles) are the five aspects of mathematics, and the latent variables (circles) represent additive genetic (A) estimates. The proportions of shared genetic influence on each of the aspects of mathematics (squared Cholesky path estimates) are shown for the first factor as an illustration. All other shared and independent influences were negligible. Applic = Mathematical Application; Underst = Understanding Number; Comput = Computation and Knowledge; Interp = Mathematical Interpretation; Non-Num = Non-Numerical Processes.
